A few more corrections have come through from readers:

On page 121, explaining the origins of the Mexican drug cartel the Zetas, I wrote: “It would be as if the Navy Seals defected from the U.S. Army to help the Crips take over Los Angeles— and succeeded.” Michael Amygdalidis emailed to point out that the Navy Seals aren’t part of the US Army – they’re part of the US Navy, so the sentence doesn’t make much sense. In future, it will say “defected from the US military.” Thanks to Michael for pointing this out.

On page 277, I refer to the city of Waunakee, where Tonya Winchester worked. She in fact worked in the city of Wenatchee. Thanks to Vito Perillo and Geoff Ashworth for pointing this out.

And although nobody has mentioned them, I also want to correct two small mistakes I realized I made in a few interviews in Australia.

I discussed the evidence that 85 percent of people who use ‘ice’ (crystal meth) don’t become addicted, and I referred to research by Professor Carl Hart at Columbia University. I learned about this research from Carl, and he has written about it himself brilliantly, and conducted other crucial research into this drug. But the original research yielding the 85 percent figure was in fact carried out – as Carl himself acknowledges whenever he writes or talks about it – by MS O’Brien and JC Anthony. It was published in the journal Drug Alcohol Dependency in September 2009, in the article ‘Extra-medical stimulant dependence among recent initiates.’ I apologize for this error: I’ll give them the credit whenever I discuss this in future.

Also, I have tried to stress in interviews I’ve done that whenever I quote from one of the subjects of my book when I speaking off the cuff, on the radio or in answer to questions at events, I’m paraphrasing them – I haven’t memorized verbatim everything they said to me. It occurred to me that I forgot to do that in some of my more recent speeches. So I’d like to reiterate that all the quotes in the book are verbatim and can be heard on this website; any quote I offer from memory when giving non-scripted talks or interviews in public may be slightly off and if you want the exact words, it’s best to consult the book, or the audio I’ve posted here.

If there are any mistakes you spot in the book, please do email me, and I’ll thank you here: the email address is chasingthescream@gmail.com
